RS232 CONTROLLER CARD FOR 
400 x 640 LCD and PLASMA DISPLAYS 
SPX20 SERIES 



CATALOG NO. SPX20/40/50/50 



The SPX20 Series of controller 
cards provide a simple and 
complete solution to interfacing 
complex flat panel displays to an 
RS232 serial data line. 

These cards provide interfaces 
for keyboards and printers and 
support a wide range of terminal 
emulations by using a plug-in 
EPROM specific to individual 
emulations. The electronics are 
based upon the use of 
programmable logic chips which 
are software controlled. This 
allows the cards to interface 
with Densitron flat panel LCD 
and Plasma displays with 
640 x 400 format. 

Various packaging formats and 
keyboard styles are available. 



SERIAL INTERFACES 



The SPX20 provides two full duplex serial ports. 
The primary port is used for communication 
with the host computer. The second auxiliary 
port is used for attaching a printer or other 
computer peripheral. The two ports can operate 
at independent Baud rates. 



KEYBOARD INTERFACES 



The SPX20 has a custom serial interface port 
designed to allow a broad range of different 
types of keyboard styles to be implemented. The 
serial interface is bi-directional and 
asynchronous. The SPX20 interrogates the 
keyboard regularly for updated status. 




CONFIGURATION OF THE SPX2 



I 



All configurations are performed on the display 
screen via the keyboard using the 'Setup Menu'. 
This technigue allows a simple modification 
without the need for access to the actual SPX20 
controller card. Changes in the 'Setup Menu' 
configuration are non-volatile. 



CHOICE OF EMULATIONS 



II 



The SPX20 can be configured to operate witr a 
wide choice of terminal emulations. The 
emulations allow all standard ASCII characters to 
be displayed in an 8 x 16 pixel block. Up to 32K 
bytes of user-defined 8x16 graphic blocks Ccin 
be displayed.
